EMBROlDERlNG-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 380,075, dated March 27, 1888.

Application filed March 20, 1886. Serial No. 195,966. (No model.)

invented anew and useful Improvement in Embroidering-Machine Attach ments,of which the following is a full, clear, and-exact descriptlon.

This invention relates to that classof sewing-machines'used for laying down and sewing upon the surface of the cloth or material to be:

embroidered, cord, braid, chenille, beading, onother embroidering material in which a unlversal feed-motion is used, as in the Bonnaz machine patented November 10, 1868, No.

83,909, said feed-motion causing the cloth to move in any direction desired, and the hooks I or needles which make the stitch to move in combination with said feed-motion, so as not 20.

. It is rather, however, as an improvement uponto change their relative positions to each other.

that attachment to such machines for throwing the chenille, 130., alternately each succeeding stitch to opposite sides of the line of stitch, secured to us by Letters Patent March 2, 1886, No. 337,088, that the invention which is the subject of this specification more particularly refers; and the invention consists in certain, means which are supplemental to the attachment described in said Patent No. 837,088 for simultaneously working duplicate strips of chenille, &c., either of the same or different colors, by throwing each strip alternately each succeeding stitch to opposite sides of the line of stitch, and so that lar to those described in our Patent No. 337,088,

also hereinbefore referred to, only a brief description will here be given of such parts as are old as is necessary to explain the present improvement or addition, and the drawings will mainly be restricted tosuch parts as are necessary to illustrate the improvement or addition and its action. a

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a partly sectional front view of so much of a Bonnaz embroidering-machine as is necessary to illustrate our invention, which is shown applied thereto; but the invention is equally applicable to other universal feed-motion machines. Fig. 2 is a vertical section of the same upon the line now in Fig. 1, looking in direction of the arrow y. Fig. 3 is a horizontal section upon the line z z in Fig. 2. Fig. 4 is aside or edge view of the device or supplementary arm or lever used for working the second or additional embroidering-strip, also showing the device carrying said lever. Fig. 5 is a similar view to Fig. 1, showing like parts, but illustrating the two levers which carry or work the two embroidering-strips in reverse positions of their throw to the positions said levers are shown as occupying in Fig. 1. Fig. 6 is a horizontal section of certain mechanism used for reciprocating the levers which carry .the embroidering-strips and for rotating them when necessary around the axis of the needlebar, and Fig. 7 is a transverse section upon the line an m in Fig. 6. Fig. 8 is a face View of a piece of cloth embroidered in accordance with our invention; and Fig. 9 is a similar view when a-center strip of braiding is used in addition to the two strips of chenille, the stitching passing through the braiding as well.

A is the needle-bar of a Bonnaz or universal feed-motion machine carrying a hooked needle, b, and having a vertical reciprocating motion imparted to it in piercing the cloth E, which is supported on the top surface, 11, of the clothplate, the needle-hook taking the thread beneath the cloth-plate and drawing it up through the cloth, then holding the thread while the feed-motion takes place, and afterward returning downward to make the succeeding stitch, an oscillating looper (not shown here) arranged below the cloth-plate operating in connection with the hooked needle for making a single-thread chain-stitch, c. Any other suitable form of stitch, however, single or double thread, may be used, if desired.

B is the reciprocating needle-bar carrier, and C the needle-bar driver, both operating, as usual, to make the stitch, and any suitable mechanism being used to actuate the driver G.

D is the ring-shaped feeder of the cloth E upon or over the top so rfacc of the cloth-plate d, said feeder being arranged to occupy a position around the needle and having a vibratory horizontal as well as avertical movement, besides a universal feed-motion, as in other machines of the description referred to.

G is the nipple surrounding the needle,'and which may be operated by the customary mechanism for holding down on the cloth till the needle has cleared the latter, but afterward rising to permit of the feed of the cloth.

The vertical and horizontal motions of the feeder D are or may be effected by means substantially similar to those in aBonnaz machine, and the mechanism which gives to themachine its universal feed-motion is or may be the same as that previously used, as also the mechanism for giving the combined turning movement to the looper and to the needle-bar carrier, and to the means connected with. said carrier which controls the direction of the feeder,in order that any'design, no matter how complicated, may be produced without turning the cloth, but by simply directing its motion by the turning of a crank or handle, as in other universal feed-motion machines. In our attachment to such universal-feed embroidering machines the strips of chenille or other embroidering material, which may be supplied from a reel mounted upon the needlebar carrier, are passed down through said carrier or through a tube, m, therein, and from thence the one strip 8 is passed to and through an eye, b, in the lower end of an arm or lever, I, near the surfaceof the cloth and within the ring-feeder D. This is the arrangement shown and described in our Letters Patent No. 337,088, hereinbefore referred to,and the lever I is simi larly hung and operated. Thus said lever I is pivoted at d to a ring, 0, arranged around .a tubular stud,f, on the under side of the frame of the machine, and through which the needle-bar carrierB works. Said lever I,which may either be all in one piece or in independent lengths adjustable one over or alongthe other to vary its length, has a vibratory motion from its pivot d as a center during the laying of the chenille s, or its substitute, on the cloth to be embroidered,for the purpose of throwing the chenille each succeeding stitch alternately to opposite sides of the line of stitch. The means used for thus vibrating the lever I, which vibration takes place in all directions of the feed, are the same as those previously used and described by us. Thus arranged around the tubular studf is a wormwheel, 0, from which alower crooked arm, 1', projects, that engages by a pin, 1?, on it with a slot, 7c, in the lever I. Gearing with this wormwheel 0 is a screw or combined screw and rack, D, that is made capable by any suitable means of having both a longitudinal sliding and a rotary motion, but which hasonly alongitudinal forward-andbackward motion when operating the wheel 0 to throw the chenille s by the lever I to opposite sides of the line of stitch alternately, as described. Thus the shaft or shank Z of the screw D is fitted to slide through a slotted guide-tube, E supactuated by one or other of the running shafts of the machine, and whereby the necessary oscillating motion is imparted to the wheel 0 to vibrate the lever I, as described, the screw D then simply operating as a rack. When, however, change is made in the direction of the feed of the machine, or, in other words, it has its universal feed given it, then the screw D is not only longitudinally reciprocated to vibrate the lever I, but said screw is also rotated or turned about its axis in the same direction as the needle-bar carrier is turned, so as always to keep the lever I or its eye I) in front of the hook of the needle I), which position is necessary to secure the proper laying of the stitch across or about the chenille as the latter is vibrated to opposite sides of the line of stitch. The means shown for thus rotating the lever I to follow the hook of the needle as it is rotated or turned, and which is done by rotating the screw D, may be asimple pulley, in", deriving its motion from the running-gear of its machine.

Nothing new is here claimed aboutthe parts and mechanism, separately considered, as thus far described.

To throw a second strip, 8, of chenille alternately each succeeding stitch to opposite sides of the line of stitch, and so that the two embroidery-strips s 3 cross each other, the one lying upon the top of the other and forming open loops a, as shown in Fig. 8, another vibrating lever, J, having a lower eye, I), for carrying the second strip, 8, of chenille supplied to it from down the needle-bar carrier, is used. This supplemental lever J, which also may be of sectional and adjustable construction in direction of its length, operates similarly to the lever I, but in a reverse direction simultaneously with I, to lay its chenille s, as described, relatively to the chenille s laid by the lever I and to thelineof stitch 0. Such joint action of the lever J with the lever I may be produced by any suitable mechanism; but to avoid complication,and to insure a synchro' nous action of the two levers I J, the lever J is shown as receiving its vibratory movement in reverse directions with the lever I by motion taken from the lever I and so that the two levers in their one stroke cross each other, as shown in Fig. 1,.and spread apart to opposite sides of the line of stitch, respectively, in their succeeding or reverse stroke, as shown in Fig. 5. Thus the supplementary embroidery-laying lever J is pivoted, as at d, to a leg or projection, g, from the ring e, and derives its motion from the opposite side of its pivot d as compared with the pivot d of the lever I, by means of a connecting-link, it. Both 1e: vers I J face or are upon the same side as the hook of the needle and always preserve such position in the turning-of the needle within the ring-feeder D when changing the direc tion of feed. IVhen, however, the feed is in a straight line or course, the levers I J are held from turning and retained in proper relationewith the hook of the needle. Thus when the feed is in a straight line or course and the needle-barand its carrier do not turn, but have simply a straight upand-down motion, the vibrating lever I, from which the lever J derives its motion, is then held from turning, so as to keep it opposite the hook of the needle,-by a slotted arm, 0', fast on the ueedle-bar carrier, and receiving through it an arm, c fast on the ring 6, which carries the lever I, as in our aforesaid Letters Patent; but as the ring or carrier 6 of the lever I (and by the arm 9 also the carrier of the lever J is free to turn about the tubular stud f, then when the needle-bar carrier is turned, as in changing the course of the feed, the slotted arm a, turning with the needle-bar carrier, operates as a driver, instead of a guide, on the arm 0* to rotate the ring e and the levers I J in common with the needle-bar carrier, so that in all manipulations of the feed the levers I J will be kept in front of the hook of the needle.

Both of the strips, 8 s, of chenille are laid By means of this sleeve the loops a, formed by l the crossing strips of embroidering material, are increased in size or width, and, if desired, similar sleeves differing in exterior diameter may be used and substituted one for the other to further enlarge or diminish the loop-like effect thus produced by the crossing and superposed" strips one upon the other secured by the line of stitching.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent--- 1. In universal feed-motion embroideringmachines, as described, the combination, with the oscillating and rotatable wheel 0 and the ring e, of the embroidery-laying vibrating arms or levers I J, pivotally connected with said ring, and the link It, connecting said levers on opposite sides of their pivots, substan' tially as and for the purpose specified.

2. In embroidering-machines having a universal feed-motion, as described, the combination, with the oppositely-vibrating embroidery-laying arms or levers IJ and the nipple G, through which the sewing-needle works, of the spring-c0ntrolled loose sleeve H, essentially as and for the purpose herein shown and described.
